AUTOMATIC TIME-ACCOUNTING DEVICE.

useful Improvement in Automatic Time-Accounting Devices, (Case 7 of. which the following is a full, clear, concise, and exactdescription, companying drawings, forming a part of this specification.

My invention relates to automatic timehas for its object the provision of a mechanism for automatically taking account of a workmans time or wages. In devices of this kind, the arrangement is usually such that a workmans reg-.

ister is actuated periodically step by step, these periodic movements being controlled either hya clock directly or by some clock governed motor. v

In the prior art the mechanisms that are used for periodically actuating the registers are so constructed that the actuations occur either at the beginning or" a periodic interval or at the end. For. instance, it a register is to be actuated every fifteen minutes, there workman is credited would be four actuations everyhour, no matter whether the actuations occur at the beginning of the quarter or at the end. Let the actuations take place it be supposed that at the beginning of the quarter hour. In this event forthe hour, let us say, between seven and eight, the register would be actuated at 7.00, at 7.15, at 7.30 and at 7.45. By this arrangement it will be seen that the with fifteen minutes in advance during every quarter of an hour. The result of this would be that should a workman disconnect his register at 11.46, he would be credited w'th the full quarter between 11.'-l5 and 12.00; the ,re ister was actuated at 11.45. other this difliculty by causing the register to actuate at the end of a predetermined interval, so that the workman would be credited with a certainperiod only after such periodhad elapsed, then this ditliculty arises: Let it be supposed that the beginning of the days work is at 7.00 and that the workmcns registers are actuated at the end of every fifteen minutes so that the first actuation would 00- On the cur at 7,15. It is evident that the Workman Specification of Letters Patent.

referenoebeing had to the ac for the reason that hand, should it be desired to escape before 7.15, as for instance, at 7.1%, would be creditedwith the full fifteen minutes lQQ'. tween 7.00 and 7.15. From these illustrations it should be plain, that no-matte'r whether a register is actuated at the beginend of such interval, it will be possible for aworkman to credit himself with time and wages to which he is not entitled. Inventors along this line have recognized this vdifiiculty and there are patents in the art which show devices for causing registrations to be made attire beginning as well as at the end of periodic intervals, and subsequently making proper corrections for the overactuations. A concrete what is meant: Assuming that the register is to be operated once every fifteen minutes, then, according to certain of the devices in the prior art, such a register would be operated at 7.00, at 7.15, at 7.30, at 7.45 and at 8;00. There would thus be five one-quarter hour actuations for every hour. The purpose of this is, of course, to compel the workman to throw in his register at the beginning of an interval, and not to throw it out before the end of the interval, if he is to be credited with that intervah By the above arrangement, if a workman were to throw his register out of operation at any time between 7 a5 and 8.00, he would not be credited with that interval for the reason that there was no actuation at 8.00. Obviously, the result of such an arrangement is that the workmans time and wage-record at the end of the day is too large. Accordingly, devices in which the actuations occur at the beginningand at the end ofperiodic intervals workmans record, at certain times, is run backward a sufiicient' amount to makethe proper corrections. This is, of course, an awkward and undesirable arrangement,

The object of my present invention is a register-actuating device whichv operates the register at the end of periodic intervals, with the provision that the workman is required to set his register-operating mechanism into actuating position at the beginning of an interval. The result of this is that although there is but one actuation during an interval, yet this actuation will not occur unless themechanism has been set into operating position at the beginning of the interval by the workman. Furthermore, according to have auxiliary: arrangements whereby the Patent-ed. Jan. 20,1914, Application filed February 24, 1911. Serial No. 610,512.

ning of a predetermined interval or at the example will make clear just turn on the shaft 1.

my invention, it a workman should during an interval throw his actuating clutch into inoperative position, it will be impossible for the clutch to make ope'ative conn ction with the register-operating mechanism except at the beginning of the next interval.

The arm is, its outer end, pro vided with a pawl pivoted thereon at 8. As seen from Fig. 1, this pawl is adapted to engage the teeth of the ratchet-wheel The arm t is furthermore provided with a casing or housing 9 within which i: secured a lug 10.

my device. I shall assaiue. :3 the. ea 2 o" illustration that the cam ?0 male; lution every li'liteen nnnnt the fU- ow in I an inter "l inina eyed for shifting this cnitehmeuilier along:

dotted lines in Fig. 3. Atthis moment the angular position of the clutch-member will be that indicated in Fig. 1; From this position of the clutch-member it will be. seen that one side of the lug 1G and the engaging port-ion 17 of the clutchduember are substair tially in alinement, so that should the clutchmember be moved toward the arm at, the lug 10 and the clutch-member will engage each other, as shown in Fig. 5, whereby the arm 4 and-the clutcl1me1nber will be virtually locked together. Therefore, as the arm 18 is raised by the movement of the cam, the clutch-member will carry with it the arm l. The parts are so proportioned that whenat the end of an interval the arm 18 is at the highest point of the cam surface and is ready io drop into its.init-ial position. the angular movement of the clutch-member and the arm 4 will be precisely'the distance of one tooth on the ratchet-wheel 2. The result is that at the end of the interval the pawl T on the arm i will drop into. the next succeeding tooth on the ratchet-wheel. The

moment that the arm 18 drops back into its initial position, the clutch-member 15 will, of course, be likewise moved back into its initial position, that is to say, into the position. in which itis shown in Fig. 1. During this forward movementof the clutch-member and the arm 4, while the pawl 7 is riding up ,the inclined surface of the en aging tooth, accidental rotation oi the ratchetwheel in that direction is prevented by the locking dog 7', which is held against the teeth of the ratchet-wheel by the spring 8'. As soon as the locking engagementbetween the lug 10 on the arm 4 and the clutch-meni- .ber isbroken, the spring 29 secured to the outer end of the arm l asserts itself and draws the arm 4 back into its initial or inoperative position. A stop 8, or any suit able means, limits the return movement of the arnui" This return or baclrverrd' movement of the arm is accompanied by a movement of the ratchet wheel whereby the register (see Fig. 2) is operated through the gears 25 and 3. Inasmuch as the angular position 0% the clutch-member begins to changei roni the very beginning of an interval and continues to change to the end of the interval, it will be apparent that at any time during an interval, thepositionlof the clutch-member,

assuming it to be in its inoperative position as shown in Fig. 2, will be such that the engaging portion 17 will havetraveled past the lug 10. So that, should the workman throw his clutch-member into operative position "during an interval, the sector portion 16 will abut against the end of the lug 10,

It will be seen that in this way there is no locking engagement eifected between the l and the clutch-member. The latter will simply move by the inwardly pressed lug without 1 producing any movement of the arm l. At the end of the interval the clutch-member will be restored to the position in which it I is shown in Fig. 1, and there will have been no actuation of the register at that moment. Should the worlnnan leave his clutch in, then at the beginning ol the new interval, the lug $16 will be freed and permitted to extend so as to is engaged by the clutch-member 15, l as shown in Fig.- 5. With the parts thus loclred together at the beginning of the inl terval, the register will be actuated at the end of the interval, as above explained. Suppose, now, a workman should throw his clutch out toward the close of an interval. The-result of this would be that the arm would be drawn back into its initial or iuoperative position without actuating the ratchet-wheel 2, for the reason that the pawl 7 would not have dropped onto the next. toot-h, this action of the pawl not occurri (r before the end cl an interval. The woi man would, therefore, receive no credit for the interval during which he threw his clutch into inoperative position. It should \be apparent" from this description of the operation of my device that it is necessary.

for a worlnnan to threw his clutch. into operative position at the beginning of an int-erval in order to receive credit for that iii-- terval, with the further provision that he operating device herein show a ctuates the register the prdper number of times during any given period. That is to say, if the register is to be actuated ever quarter of hour, there will be only four actuations luring'that hour, one at the end of every piarte".

Various other results and effects may be accomplished by my invention. For. instance, by causing the forward swing of the clutch-member to equal the. space of more than one tooth it is possible to make a beginning period diti'erent from an ending period. This may be best explained by as suming a concrete illustration. supposed that the clutch-member moves forwardly during every half hour the distance of two teeth. In this way the beginning period is equal to half an-hour, whereas the ending period will amount to fifteen minutes only. That is to say, a workman who has not started by seven in the morning will receive no credit untilTBO and thereafter. If, however, he works until 11.46. he will get or.

dit tor the f fteen minutes between 11.30 and 11.45. "because when he throws his clutch out of 01 position at 1146, the pawl T of the arm 4: will have dropped into the next" succeeding tooth, whereby, when the arm is released, it will be drawn back by the spring 29 the distance ot' one tooth. In this way the register would in Fig. Gare the same as those shown in the "member 38-01. this differential other figures, and already described above, I shall simply refer to'the gearing arrangement in this figure. The gear 8 of each reg ister-operating mechanism engages with a gear which gear in turn engages with a gear for driving the associated register. The sleeve 3st loosely mounted on theshaft 3.3. The other end of the sleeve 34 has secured thereto one member 36 of a differential gear indicated as a whole by 87. As shown in the detail views of Figs. 7 and 8, the central set has journaled therein two pairs of pinions 39, and 4:1, 4:2, respectivelyQ The shaft of each pinion is at its end journaled in the housings Lt and secured to the central gear 3.8. The pinions 39 and 40 constituting one pair are in mesh with each other, and the )inions 41 and 4:2 constitutin the second pair a e in mesh with each other. Although I have shown two pairs of these pinions, it is clear that one'pair only might be used. The pinions 39 and 41 are in engagement with the teeth of the gear wheel 36. while the pinions 4.0 and 42 are in mesh with the teeth of the gear wheel 36". The proportionsoi'f the various parts of this differential gear mechanism are such that the rotations of the gear wheels 36 and 36 will be added by the central member 88 and transferred into the gear 44 of the summatioirregister AB. The actuations of registers A and B will,

therefore. be totalized in the summationregister AB. Similarly, will the aetuations of registers L and M'be totalized into the summahon-register LM. Should further totalization bedesired, the difierential gear connection above described may be extended to the summation registers AB and LM so as to totalize the actuations of these two registersinto a finalsummation-register. Various other arrangements of the registers will suggest themselves to those skilled in the art.

Although I have shown a specific struc ture to illustrateimy invention, I would have it understood that such illustration is merely by way of example, and that various alterations and modifications may be made in many of the details to carry out the essence of my invention. Thus, for instance, the

gear 32 is connected to one end of a aoeagese clutch-member may be of any suitable form other than-that shown in the drawings. So also may the part designated by 3 and herein called an arm take the form of. for instance, a disk. Also, the differential gear ing herein shown may be substituted by any other desirable form.
